EASY Bitcoin Privacy | Fake Coinjoin for transactions using Sparrow Wallet

本站添加: 2026-05-30

[00:00:00]Privacy with Bitcoin is a challenge.

[00:00:03]It's a problem that is actively being worked on, developed, and there are some tools that do make privacy possible, but they're not really that easy. It doesn't come naturally to the way that Bitcoin is designed. But, if you're here, you probably are a little more advanced when it comes to Bitcoin and you're looking to use it privately, and that's what this tool is designed for. This is called a Stonewall transaction or a fake coinjoin, and this is for specifically paying somebody else and creating probabilistic links so that it's difficult to actually use chain analysis to see who owns what and what's actually going on with your Bitcoin. Bitcoin is this big large transparent pool of transactions, and you could look into those transactions and not know who's transacting cuz it's all just addresses and transaction IDs, but if somebody has your information, like if you bought this on Bitcoin on a KYC exchange, it does create some issues using those privately. I'm going to show you how to do these transactions really simply.

[00:01:09]It's incredibly easy using Sparrow Wallet, and I'm going to talk about a little bit of the prerequisite so that you can do this effectively and you can make your transactions with Bitcoin more private. My name is Forrest Hodel. I'm a Bitcoin educator, and I do one-on-one coaching for anybody looking for some additional help with their Bitcoin best practices, making sure you have the best security that you can, making sure that you are ready for inheritance and multi-sig, whatever you need help Bitcoin related, I can help, and my link for that is in the description. It's pathtobtc.xyz.

[00:01:42]I also run the Bitcoin Masters online learning community, which is linked below as well. If you want to meet some amazing other Bitcoiners and get some exclusive lessons and courses through there. So, we're going to be doing this transaction using Sparrow, and I'm going to show you how to do this. There's one prerequisite that I think you should really take into account before doing this, and that is making your Bitcoin as private as possible or as de-linked from your KYC as possible prior to using this. This is for sending Bitcoin. So, when you're sending Bitcoin this way, you're creating additional guesswork that has to happen for anybody to track what's going on. So, they see multiple transactions, they see multiple inputs, and they're not exactly sure who's involved in this. And this looks like a two-person coin join, but in fact, it's actually just you constructing what looks like a two-person coin join. And there's two outputs that are the same, and somebody looking at this transaction doesn't know which one is the real transaction and which one is just actually the change address. It's going to be a little more obvious and understandable when I actually do this, but I just wanted to explain that ahead of time. So, to de- So, to de-link yourself from the Bitcoin that you use in this, you should use a coin join ahead of time using, say, Wasabi Wallet, which I have a link in the description, uh a video on how to use that. Or you could buy your Bitcoin peer-to-peer and have it non-KYC from the start. Okay, so this is my test wallet here. This is my hardware wallet test wallet. You can see that some of these have some privacy scores. I've been using these for all sorts of different things here. Uh these are my UTXOs here. I have four different UTXOs with different privacy levels.

[00:03:20]But, we're going to assume all of these have been coin joined. All of these have been de-linked. That's where you want to start with this spending wallet. Now, what we're going to do is we're going to go to the send tab on the left here.

[00:03:32]We're going to put in a receive address.

[00:03:34]I'm actually just going to copy this receive address. So, I'm just going to send this to myself as an example, but this would be sending to someone else.

[00:03:42]Let's do fake coin join. This is a internal label. This doesn't actually ruin any sort of privacy. This is for for own sake here. So, let's try to put some in here. So, let's go 6767.

[00:03:55]We can do even amounts. We can do odd amounts. It uh should work.

[00:04:00]What you need for the privacy transaction is you need around double the amount of Bitcoin in your wallet compared to the actual amount that you're sending because you're going to be sending more Bitcoin. So, we can see here. Let's Let's take a look. The amount of fees to send this transaction is in an efficient way is 209 at a one sat per vbyte. And that's because I have these two UTXOs it's taking from and then it's creating a uh transaction here and a change address. So, this is fairly typical. If I did a little bit less, it could just be from one of these instead.

[00:04:42]Um even even we could actually take a look at this. If we just do 4,000, it's going to be even cheaper because it only needs to draw from one address. So, it only has one input. It takes up less space. So, let's actually do that. Uh this is our example. So, in an efficient way, we're paying 141 sats to do this transaction and it is creating this transaction and this change address and they're both different amounts. Now, all we need to do to make a fake coin join or a stonewall transaction is to press this privacy button.

[00:05:15]Now, what this looks like instead, you can see here we have this UTXO. We now have this UTXO as well being added to it. And we have a bunch of outputs.

[00:05:27]What we have here is we have the actual transaction that we're going to be sending. We have a fake mix. So, this is another transaction with the same amount of uh Bitcoin, right? 4,000 satoshis.

[00:05:41]And then we have two different change addresses that are part of this output.

[00:05:46]So, there's a lot more going on here and specifically this fake mix is here. So, now somebody looking at this can see that I sent Bitcoin uh if they know who this is or they can just look at this transaction, they can see, "Okay, well, I don't know which one of these is the actual payment." Because there's just more transactions. It's creating fake transactions.

[00:06:09]And the amount of satoshis that I'm paying for fees has basically doubled. So, 141 to 272.

[00:06:18]And that's because there's more inputs and there's more outputs. So, we're creating a larger transaction, which is going to take up more space in the blockchain. So, I'm going to do this transaction now and we're going to take a look at what we have coming out of it.

[00:06:33]So, I'm just going to finalize this and I'm going to uh scan my QR code. Here we have it. We have the signed This is the fake coinjoin signed PS BT and we're going to load that in. We're going to broadcast this now and we'll just wait for our node to connect and everything to go through and then we'll take a look at what we receive on the back end. All right, so that has been sent and we have this here. This is unconfirmed.

[00:07:03]We have two inputs, four outputs.

[00:07:06]And let's take a look at our UTXOs now.

[00:07:09]So, we have the unconfirmed UTXOs here.

[00:07:13]We have the two fake coinjoins. One is This received one means that this is actually me sending somebody else the Bitcoin. This would be to the address that I wanted to send to. The change is actually received back to me in a new address, but again, looking at the public blockchain, you cannot tell who this would be to. You don't know if that's the Bitcoin that somebody else received or that I received. So, you have this anonymity set really of two here. You also have some change back as well and some change here as well, 35,000.

[00:07:50]So, let's take a look in the mempool here. We're pasting in this transaction.

[00:07:54]We see the fee rate we paid. We see the total amount of fees and then we see this.

[00:07:59]So, we have two inputs. We have four outputs and a fee.

[00:08:04]And this is what it looks like. So, now somebody doesn't know they don't know looking at this which one's a payment, which one's a change address, and what's going on really here. They can just see that these two are the same, this 4,000 and really it's uncertain who's received it and what's a change address here. This is a great tool in my eyes. This is incredibly easy. It's literally the click of a button. Yes, you're going to pay a little bit more fees, but now you have some privacy to the transaction part of Bitcoin, of sending Bitcoin and creating some privacy within there. So, this essentially mimics a two-person collaboration. This looks like two people coin joining. So, analysts can't really definitively know that these UTXOs are owned by one person unless those UTXOs are already known to be owned by one person. So, that's why it's important to have non-KYC Bitcoin or de-linked Bitcoin through a coin join to be using this kind of technique to begin with. So, privacy starts before using this, really. So, just remember that this is really a spending tool to create some privacy. It's not a mixing tool. It is not a replacement for Wasabi or some other coin join. It is designed to be used after the KYC link is broken. So, hopefully this was helpful and I hope that more people end up using tools like this because the more people do, the more private Bitcoin becomes for everybody as we start to de-link coins and as we start to create some confusion for, you know, these chain analysis type organizations that are actively trying to link people's coins together. So, we got to do our part by activating and using privacy tools. And of course, there's going to be better and more private ways to use Bitcoin in the future and a lot of that will be built on layers. Lightning is already a lot more private. You know, there's all sorts of really cool innovation happening, but at the base layer, privacy is still quite difficult and this is a base layer transaction that adds at least some levels of privacy based on the scenario of those coins. So, thanks everybody for watching and I also want to thank everybody who's been hiring me to help them with their one-on-one consults, making sure that you have the best Bitcoin security. Everything you guys do when you watch these videos to liking, sharing, again, checking out all the links in the description for all the Bitcoin related things that you need as a Bitcoiner, all of that really supports this show. It really supports me being able to make more of these and makes it so I can spend time, energy, and effort on producing education to hopefully orange pill the masses. Thanks, everybody, and we'll see you on the next one.
